10 applications, 6 months life... thats 5 years of decent protection for 150 quid.

I thought it was really expensive til I thought about it a bit more.
Shame I havent got access to a power supply. Do they make DA buffers that run on batteries like cordless drills?

One point though, its a shame detailing and polishing companies such as yourselves only tend to demo your products on already decent cars. A better real test would be to get in a 20 yr old mk2 fiesta in radiant 'pink' and polish that up. Thus you'd have a sensible before and after experiment. Making a 'new' car shine looks all too easy to my non-expert eye.
